Question on blue dragons and earth subtype

[Barnak]

Hi everyone! We're adapting Council of Wyrms for Pathfinder and I play a blue dragon in it. When I looked at the blue dragon, it says that it is of the earth subtype and has a burrow speed. When I looked at the description, it says that earth creatures with a burrow speed also have tremorsense. The problem is that the dragon doesn't have tremorsense. Is it only creatures made of earth?

Thanks!

I don't get that impression from the text. At a guess I would say that it's probably an error in the Blue Dragon entry, and that they should have tremorsense as well.

Sorry I did not answer your question properly in my original post. Blue dragons do not have tremorsense because all true dragons have blindsense which includes all the benefits of tremorsense I believe.

Smaug certainly casts a long shadow over his RPG progeny, doesn't he?

From the look of it, they aren't.

Blindsense : "The creature usually does not need to make Perception checks to pinpoint the location of a creature within range of its blindsense ability, provided that it has line of effect to that creature."

Tremorsense : "A creature with tremorsense is sensitive to vibrations and can automatically pinpoint the location of anything that is in contact with the ground."

That means that a creature with blindsense can't feel an opponent on the other side of a wall and can't always pinpoint the opponent.

To me, it's not the same and if it's not, what's the range the dragon should have? 60 ft?

The Crystal Dragons in Bestiary 2 specifically call out gaining Tremorsense at the Young age category. Make of that what you will.

Probably an accidental omission from the blue dragon entry. A blue dragon is both an earth creature and has a burrow speed -- I would assume that the rules for the earth subtype "add on" to the blue dragon. I'd set the tremorsense at 60 ft.

Thread Necro, but related: Can blue dragons burrow through stone? From the Earth subtype: Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.

Figured I would ask here rather than create a separate thread. Till I get a little more desperate at least. This has rather significant impact on my Osirion game.
